Approach 1: Clean Harbors Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a company might generate in the future and discounts those cash flows back to today, aiming to arrive at an estimate of what the business could be worth per share right now.

For Clean Harbors, the model used is a 2 Stage Free Cash Flow to Equity approach. The company’s latest twelve month free cash flow is about $372 million. Analysts provide explicit free cash flow estimates for the next few years. Beyond that point, Simply Wall St extrapolates the path of cash flows, reaching a projected free cash flow of $793 million in 2030. All of these cash flows are in US$ and are discounted back to today in the model.

On this basis, the DCF model suggests an estimated intrinsic value of about $360.25 per share. Compared with the recent share price of $265.98, the model implies the stock is about 26.2% undervalued.

Approach 2: Clean Harbors Price vs Earnings

For a profitable company like Clean Harbors, the P/E ratio is a useful way to see how much investors are paying for each dollar of earnings. A higher P/E can reflect stronger growth expectations or lower perceived risk, while a lower P/E can point to more muted growth assumptions or higher uncertainty.

Clean Harbors currently trades on a P/E of 36.59x. That sits above the Commercial Services industry average of 26.08x and below the peer group average of 46.15x, so the stock is priced between the broader industry and closer peers. Simply Wall St also calculates a Fair Ratio of 26.26x, which is the P/E it would expect given factors such as earnings growth, profit margin, company size, industry and specific risks.

This Fair Ratio aims to be more tailored than a simple industry or peer comparison because it adjusts for the company’s own profile rather than assuming all Commercial Services businesses deserve the same valuation. Comparing the Fair Ratio of 26.26x with the actual P/E of 36.59x suggests Clean Harbors shares are trading above this modelled level.

Upgrade Your Decision Making: Choose your Clean Harbors Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, which bring your view of Clean Harbors together with the numbers behind it.

A Narrative is simply your story about the company, backed by your own assumptions for fair value, future revenue, earnings and margins, instead of relying only on a single model or market multiple.

On Simply Wall St, Narratives live in the Community page and link that story to a financial forecast and then to a fair value. This allows you to easily compare that fair value with the current share price and decide whether Clean Harbors looks attractive, fairly priced or expensive based on your view.

Narratives on the platform are refreshed when new information such as earnings releases or news is added. Different investors can hold very different views on Clean Harbors. For example, one Narrative might point to a materially higher fair value than today’s price, while another suggests a materially lower figure based on more cautious forecasts.
